ANTISLIPPING DEVICE.

Application filed November 16, 1928. Serial No. 319,851.

This invention relates to an improved antislipping device adapted for attachment to the bottoms of boots and shoes to prevent the wearer from slipping on icy sidewalks and the like.

The primary object of the present invention is to provide a simple and efficient device of the above kind which may be conveniently carried until required for use, which may be readily and effectively attached to the shoes for use or stripped therefrom when no longer required for use, and which may be cheaply manufactured and sold at such a nominal cost as to render it practical to throw away ordiscard used ones when removed.

The invention consists in the novel construction hereinafter described, shown in the accompanying drawing, and claimed.

In the drawing Figure 1 is a side view of a shoe with the anti-slipping pads of the present invention applied to the bottom thereof.

Figure 2 is a bottom plan view thereof.

Figure 3 is a perspective view of the antislipping device with the adhesive-protecting covering applied to the pads; and

Figure 4 is an enlarged transverse section on line 4-4 of Figure 3.

The present device consists of felt pads or thick felt sheets 5 and 5 respectively shaped to conform to the outline of the sole 6 and heel 7 of the .shoe 8, but preferably slightly smaller as shown. The upper surfaces of the sheets 5 and 5 are completely coated with a suitable waterproof adhesive as at 9 adapted to cause the sheets to effectively adhere to the shoe bottom when n pressed against the latter. The adhesive 40 surfaces of the sheets 5 and 5 are normally protected or covered with a sheet 10 of course mesh cotton fabric so that the device may be conveniently carried until required for use. The natural rough and porous lower surfaces of the sheets 5 and 5* effectively prevent slipping without the use of applied or attached friction elements or substance, and due to the relatively thick nature of the sheets and their coverings of waterproof adhesive considerable protection from dampness is had by the wearer. The protecting sheet 10 has a projecting margin to facilitate removal thereof when the pads or sheets are to be used.

From the above description, it will be seen that the device can be conveniently carried and readily applied to the shoe bottom, and that it will furnish a very cheap and efficient anti-slipping pad or sheet which may be torn off of the shoe and discarded when no longer required for use.

I claim:

1. An anti-slipping attachment for the bottom of a shoe, comprising a thick sheet of felt shaped to conform to the outline of 5 the sole bottom and having its upper surface coated with a waterproof adhesive adapted to cause the sheet to adhere to the shoe bottom, said sheet having a natural rough lower surface to prevent slipping.

2. An anti-slipping attachment for the bottom of a shoe, comprising thick sheets of felt respectively shaped to conform to the outline of the sole and heel of the shoe and having their upper surfaces coated with 75 a waterproof adhesive adapted to cause the sheets to adhere to the shoe bottom, said sheets having natural rough lower surfaces to prevent slipping, and a detachable protecting sheet of thin fabric covering the ad- 30 hesive coating of the said sheets of felt,

In testimony whereof I affix my signature.
